superstruct-extra v0.2.0

superstruct-extra

Extra types, refinements and coercions for superstruct.

Reason

Superstruct is a great library, but sometimes you need additional types.

This re-exports superstruct as well as the following additions.

• promise() - for adding promise values which can be verified.
• fn() - for typed function declarations.
• bigint() - add support for bigint.
• args() - create args for the fn type.
• nullish() - add support for null | undefined. This can also be used for void types when creating fn schema.
• nonempty() - refine arrays, strings, tuples and maps to ensure they are nonempty.
• email() - refine a string as an email - this comes with a special Email type based on annotating the string type.
• uuid() - refine a string as a uuid.
• readonly() - refine iterables and objects to be readonly. This doesn't perform any client side enforcement of readonly properties.
